Well, within a couple of years, we all knew.
Jimi seemed so strong, so in-control. But that was an illusion. All of the tensions of the age didn't sit well on him; all of the racial bullshit hit him hard from all angles. I'm afraid that even the well-deserved praise was a mixed blessing for Jimi.
Whatever really happened, it was a tragedy. Jimi was unique. I am not the final arbiter of such things, but musicians such as Jimi are rare. They show up at long intervals. Some, like Beethoven, have long and varied careers. Others, like Jimi, appear and burn out quickly. At least Jimi was extensively recorded.
He'll be with us always. I'm grateful for that.
